To aZZ 'whom it, may concem:V v

Be it knownithat we, WILLIAM. REUsoI-I,

HENRY ALTHEIDE, and PAUL REUsoH, citizens ofk the -United States,residing at Anaheim, in the county of Orange and State of California,have invented certain new andv cases o-f engines, such yas are usuallyemployed for propelling vehicles, whereby the air drawn into the enginecrank case will be thoroughly filtered and freed of dirt, dust, sand,and otherv foreign matter, which when admitted tothe crank 'case willmix with the lubricating oil circulating therein and be cause of itsabrasive action upon the various bearing surfaces therein effect,premature deterioration of the same.

Among other objects of the invention may be recited, the provision of adevice vof the character mentioned with a view towards compactness, andVin which the number of parts is few, the construction simple, the costof vproduction small and further, a device which may be attached topractically all forms of prevalent types of engines with but slightalteration thereto.

Other objects will be in part obvious and in part pointed outhereinafter.

In order that the invention and its mode of operation may be readilyunderstood b-y persons skilled in the art, `we have in the accompanyingillustrative drawings and in the detailed following description basedthereon set out one possible embodiment of the same.

In these drawings Figure 1 is a side elevation of the improved breatherdevice applied to a fragment of an engine crank case;

Figure 2 is a vertical section through the same' Figure 3 is ahorizontal section therethrough taken on the line 3 8 of Figure 2looking in the direction in which the arrows point; and,

object to provide a novelform of breathery lter.

Having more specific reference to the drawings, in y connection withwhich like characters of reference will designate corresponding partsthroughout7 we have shown our improved breather device as applied to,the crank case of an engine, fragmentally-- shown and indicatedk by thenumeral 1, said crank oase having an opening formed therein adapted toreceive the usual breather.

' Our improved rbreather comprises a housing divided intojuxtaposedchambers 2 and` 3, the upper ends of which are opened andinternally screw threaded whereby to en-y gage correspondingly screwthreadedcaps In' this connection, it istobe noted 4 and 5. that thecommunication as between the juX- taposed chambers 2;-and 3'* of thebreather device is established by way of a port 6 formed in theintermediate wallofthe chambers, and

because of the fact that a plurality of ori-V fices or ports 7 areformed in the lower endv of the chamber 3, which as'will be noted, isofless size than thechamber 2, air will be permitted to be drawn into saidcharn-` ber?) and from there throughthe port 6 into the chamber 2 forA'discharge intothe crank case 1 byway 0f thereduced open lower end S ofthe chamber 2 which lower end, as will be noted, is of a sizesuch aswill' insure its snug receptance in'theopem'ng formed in the crank case;the annular shoulder formed by f said reduction resting upon theadjacent portion of said crank case,-

In orderl that the breather device housing may be securely connected tothe crank case 1 and held thereupon against any undue movement orvibration, a spider 9 is arranged within the chamber 2, preferablyintermediate its upper and lower ends and receives through a centralopening formed Figure is 'adetailpin perspective of the therein theupper screw threaded portion of a connecting or tie rod 10, the lowerend of the rod being hooked as at 11 and adapted to engage with atransversely disposed anchoring bar 12 which is arranged in the crankcase 1 and has its opposite ends engaging adjacent portions of saidcase. Thus, with engagement of the nut 13 with that portion of theconnecting rod 10 extending above the 'spider 9,'the hook 11 will beengaged with the anchoring bar 12 and upon tightening of the lockingscrew 13 will effect the clamping of the breather device housing inrposition upon the crank case 1, with the necessary degree of rigidity.

Removably positioned in the chamber 6 is perforate cylindrical shell 14having the will permit of its snug reception in the chamber 3 and byconsequence, with arrangement of the filtering means over the orifices'7, such air as passes therethrough into the chamber 3 and through theport 6 in the chamber 2 for passage into the crank case 1 will bethoroughly filtered, since it must necessarily pass through theiiltering matter 16. Therefore, it is to be understood that the airdelivered into the crank case 1 by way of our improved breather devicewill be thoroughly filtered and thus, relieved of dirt, dust or sand orthe various other foreign matters which `upon mixing with the oil to anymaterial extent will cause the same to have detrimental eect upon thebearing surfaces coated thereby.

In using our improved breather device, oil may be readily introducedrinto the crank case 1 by merely removing the closure cap fi from theupper screw threaded extremity of the casing. Then it is needed thefiltering means contained in the perforate shell 111 may be replenishedby removing the same through the upper end of the chamber 3,

the closure cap 5, of course, having been previously disengaged from itsscrew threaded upper end. If necessary it may be entirely removed andrenewed.

Manifestly, the yconstruction shown is capable of considerablemodification and .such modification as is within the scope of ourclaims, we consider within the spirit of our invention.

IVe claim: y

1. A breather pipe comprising a pair of substantially cylindricalchambers communicating with each other near their upper ends, removableclosure members for the upper ends of said chambers, the lower ends ofsaid chambers being provided one with an air inlet opening and the otherwith an air outlet opening, and filtering means removably mounted in oneof said chambers.

2. A breather pipe comprising a pair of substantially cylindricalchambers communicating with each other near their upper ends, removableclosure members for the upper ends of said chambers, the lower ends ofsaid chambers being provided one with an inlet opening and the otherwith an air outlet openino, a perforated shell removably arranged in oneof Said chambers, and filtering material arranged in said shell.

3. A breather pipe comprising a pair of substantially cylindricalchambers communicating with each other near their upper ends, removableclosure members for the upper ends of said chambers, the lower ends ofsaid chambers being provided one with an inlet opening and theI otherwith an air outlet opening, a perforated shell removably arranged in oneof said chambers, filtering material arranged in said shell, a rodmounted in the other of said chambers, said rod projecting through saidoutlet opening, and having a hook formed on its end, and a transversemember arranged in the' crank case, and adapted to be engaged `by saidrod to retain the device in position.

In witness whereof we have hereunto set our hands.
